Group slow

Hi, when i open a light directly ( ex : light.kitchen ) it open right away BUT it I setup many light in a group ( ex: group.livingroom ) it super slow.

It open all the lights one by one instead of all at the same time… I have 2 tuya light each side of my tv… So each time i try to open the lights it start the by opening the left light then like 1 or 2 second late the right light start …

Is there a beter way to do it ?

grouping lights will allow you to issue a single command to HA to turn all lights on, but HA still needs to issue individual commands to each lights, so yes they will light one after the other, you won’t be able to change this. Unless you convert your TUYA to MQTT and assign the same mqtt topic to each light… but then you can’t have only 1 on, they will always work in pair…
